Why won't my 60fps videos upload in 60fps?

I have tried a number of different options based on research I have done, but nothing I do seems to work. Let me explain.

I record gameplay from Xbox One using an Elgato HD60 Pro capture card and OBS. In OBS, my I set my capture to 1920x1080, 60fps, and 12000k bit rate. I then load the footage into Windows Movie Maker to do some editing. Once I'm done editing, I export the video as an MP4 with the custom settings of 1920x1080, 60fps, and 12000k bit rate as well.

When I upload the videos to YouTube, it initially only shows up in 360p while the higher resolutions process. After all is said and done though, the videos only go up to 1080p in 30fps. No 720P 60fps or 1080p 60fps.

I have tried a number of solutions, including messing around with the bit rate and removing intros from my videos (which were rendered in 60fps anyway so that really shouldn't matter) but nothing has worked so far.

Does anyone know why I can't upload in 60fps?

Thanks in advance
